T3 Series Front Turn Signal Upgrade
Why Upgrade to T3 Series?
Built-In CANbus Decoder
A ceramic resistor is integrated directly into the bulb to help eliminate hyper flash and dashboard warning errors without requiring separate external load resistors.
Up to 2000LM Per Bulb
Each T3 bulb uses 20 high-output 3030 SMD LED chips and delivers up to 2000 lumens with a maximum 24W output for more noticeable front signaling.
Quick Plug-and-Play Installation
Compact dimensions close to the factory halogen bulb make the upgrade straightforward without external resistors, special tools or complicated rewiring.
Intelligent Cooling System
A full aluminum body, eight heat-dissipation openings and a smart temperature-control chip help manage heat and maintain stable performance during regular use.
Switchback vs. Amber Front Turn Signal
The lighting function changes by model year, so select the option designed for your truck rather than choosing by bulb size alone.
